Reviews From Southern NH Homeowners
I have had A.J. LeBlanc Heating install and service all my HVAC equipment and recently they installed a Daikin mini split and we absolutely love it and the warranty is 12 years unbelievable. I have recommended this company to many of my friends.
Mary BergerDuctless Mini Split customerThe crew arrived on time and quickly got to work replacing our gas furnace and air conditioning unit. They finished up before we knew it and cleaned up after themselves. They were very professional and polite.
Bruce JelleyA/C Installation customerAfter having A.J. LeBlanc Heating do an installation of the AC mini-splits about a year and a half ago, I decided to check with them first about replacing my boiler which was 30 years old. I requested the same salesman and was glad to have the continuity of someone familiar with my needs. The technicians who came to do the boiler installation were great - one was the same who had been here with the mini-split installation, so I felt comfortable that the job would be done perfectly and I was not disappointed. I would recommend A.J. LeBlanc Heating for service anytime!
